雪 — rain 雨 + hand 彐 (originally broom 帚)
Originally an ideograph showing rain 雨 above a hand holding a broom, suggesting snow as 'rain that can be swept.' Over time the broom element simplified to 彐. The character has always meant snow, with later extended senses like 'to wipe away' (as in 雪恥, to wipe out shame).
